Field of the Invention This invention relates to toy racing vehicles and more particularly to toy racing vehicles which are impelled by a spring biased launching implement.

2. Brief Description of the Prior Art Spring propelled devices in many forms are well known in the toy field, including spring propelled toy vehicles. Specifically, it is well known to provide a wheeled toy with spring means designed to act against a propelling element for the purpose of causing the vehicle to be propelled across a surface by reaction force in response to the release of the spring by manually operated means of some kind. Also known in the art are spring propelled vehicles wherein the spring propelling device is provided for in a separate launching implement or platform as disclosed by Holt in Us. Pat. No. 2,803,922.

Also known in the art are toy gun devices which will eject a simulated empty ammunition shell after the toy gun has been fired as disclosed by Ferri in US. Pat. No. 3,304,644.

It is an object of this invention to provide a new and useful toy vehicle and launching implement combination. The launching implement is formed in the shape of a toy gun, or rifle, and will eject spent ammunition shells after the device has been fired.

Another significant object of the invention is to provide an interlocking means on the launching implement such that it cannot be fired under unsafe conditions. The interlocking mechanism requires that the launching implement be placed flat on the floor before it can be fired. This mechanism also prevents firing of the launching implement when it is not loaded and especially when it is not loaded with the toy vehicle and shell combination provided. More particularly this mechanism will prevent the launching of any small objECIS, such as stones, marbles, pencils, or the like, which are not of the same size and shape of the intended projectile.

Additional objects and advantages of the invention will appear after the description hereinafter set forth is considered in conjunction with the drawings of the invention.

SUMMARY OF THE INVENTION This invention is directed, in brief, to an improvement in toy devices wherein a small racing car is impelled along a flat surface by a launching implement.

The best mode currently contemplated for carrying out the invention includes a small wheeled racing car which is fitted into a simulated ammunition shell, and a launching implement in the form of a simulated rifle is provided to impel the car over a floor. The launching implement includes a srping biased plunger which is depressed or cocked by the forward movement of a bolt-type mechanism similar to that type used on single shot rifles. An opening is provided in the sideof the launching implement for loading the car and shellcombination into the launching implement. When. the bolt mechanism is cocked, it contacts the shell and racing car combination and pushes them into a firing compartment near the front portion of the launching implement. The plunger, which is released by pulling a trigger, strikes the rear portion of the racing car causing it to roll down a ramp and out of the launching implement onto the floor. The shell is retained in the firing compartment and, when the bolt mechanism is retracted for reloading, a small hook on the end of the bolt mechanism pulls theshell from the firing compartment and ejects the shell through the opening in the side of the launching implement.

A three part interlocking mechanism is provided such that the operator cannot fire the launching implement under unsafe conditions, particularly prohibiting firing the vehicle through the air. The trigger will not operate unless the impelling instrument is supported on a flat surface, a spring biased safety latch is held open,

and a race car is loaded in the firing compartment. Thus, both hands of the operator are required to operate the launching instrument thus preventing a race car from being fired into the air, and also preventing firing of the instrument when projectiles, particularly small or unsafe projectiles such as pencils or the like, not of the same size and shape of the race car are loaded in the launching instrument.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIG. 2, the toy device is shown in i a position ready for launching the toy vehicle 14. The launching implement 12 includes a relatively large, hand held generally hollow frame 18 simulating the shape of a rifle. A trigger 20 is pivotally mounted on a pin 22. which is integrally molded with the frame 18.

The trigger also is provided with a curved slot 24 and two posts 26 and 28. A leaf-type spring 30 is attached to post 26 and is inserted into a slot provided in another post 32 molded integrally with the frame 18 such that the spring 30 causes a counterclockwise force to be applied to the trigger 20. The slot 24 provides a guide for the trigger 20 along post 32.

A release lever 34 is mounted on a pin 36 such that it will release a cross-shaped elongated plunger 38 when the trigger 20 is pulled. A curved flexible portion 40 is provided on the release lever 34 to return the lever to its original position by engagement with the post 28 on the trigger 20. A cylindrical interior bolt housing 42 encloses the plunger 38 and a spring 44. The spring surrounds plunger 38 such that the spring 44 is compressed when the rear headed tip 46 of the plunger engages with lever 34 and the bolt housing 42 is in its forwardmost position. The front tapered tip 48 of the plunger 38 is provided with a disc-like flange 50 which contacts a rubber damping gasket 52 at the front of housing 42 when the plunger moves forward under the force of the spring 44. The front tip 48 of the plunger strikes the rear of the toy vehicle 14 causing it to be impelled down a flanged ramp 56 and out the front open end 58 of the impelling rifle-like instrument 12.

The rear tip 46 of the plunger 38 engages with the tip of the lever 34 when a bolt arm 60 is moved upwards and toward the rear in the direction of arrow A shown in FIG. 5. For convenience. a round ball-shaped handle 62 is provided on the end of the bolt lever 60.

A sight 63 is rotatably mounted by means of a pin 64 in a flange 65 extending upwardly on the top of the frame 18. A sighting protusion 66 is provided on the top of the frame 18 near the front end 58 of the implement to aid in aiming the travel of the toy vehicle 14.

To load the launching implement. a toy vehicle 14 is fitted into a shell 16 and placed in a loading compartment 67 provided for by an opening 68 on the side of the launching implement 12. The launching implement 12 is cocked and readied for firing by pushing the bolt arm 60 forward and down in the direction of arrow B shown in FIG. 5. The front end of the bolt housing 42 engages with the rear of the shell 16 and pushes it into the firing compartment 67a as it compresses the spring 44 between the circular disc 50 on the front portion of the plunger 38 and the rear portion of the bolt housing 42. The launching implement then is ready to be fired, as shown in FIG. 2.

FIG. 8 shows a perspective view of the toy vehicle 14 and the simulated ammunition shell 16. The shell 16 is generally tubular in shape with a flat bottom portion 69. A slot 70 is provided for clearance of rear wheels 72 of the toy vehicle 14. In addition. a hole 74 is provided in the bottom flat portion 69 of the simulated shell 16 to engage with a detent 75 on the bottom of the toy vehicle chassis 76. A circular base 78 is provided on the end of the simulated ammunition shell 16 with a diameter slightly larger than the diameter of the tubular portion of the shell to retain it in the firing compartment 67a.

Referring to FIGS. 9 and 10. we see the toy vehicle comprises a hollow body formed of plastic or other suitable material in the shape of a large scale bullettype projectile. The body 90 is mounted on the chassis 76. The chassis is fabricated of metal, or the like, which gives the toy vehicle a low center of gravity to increase its accuracy when moving over a supporting surface. The chassis 76 carries the rear ground engageable wheels 72 which are fixed to a common axle 92 for conjoint rotation therewith. The axle is rotatably mounted in a bearing 94 in the rear portion of the chassis 76. Thus, the wheels are not independently rotatable and, preferably, have rubber or other friction surfaces. A generally triangular cut out 96 is provided toward the front portion of the chassis for clearance with a front wheel 98 which is supported by an axle 100 carried by a yoke shaped caster 102 which is pivotally mounted to the body 90 by a screw 104. The front wheel is weighted, as by being fabricated of metal. The combination of the weighted, caster-type front wheel and the rear wheels 72 fixed to shaft 92 for conjoint rotation causes the toy vehicle 14 to travel over a floor, or the like, in a very straight path. This allows for accuracy in aiming.

The detent 75 is provided on the rear portion of the chassis 76 to engage with the hole 74 in the bottom portion of the shell 16 such that the toy vehicle 14 and the shell 16 may be loaded as a unitary member into the launching implement 12.

A sound producing device for the toy vehicle is provided in the form of a gear type member 106 fixed for rotation with axle 92. A resilient leaf 108 is mounted for engagement with the teeth of member 106 for producing sound as the rear wheels and axle 92 rotate.

A safety interlocking mechanism is provided, generally designated 110 (FIG. 2), and shown in FIG. 7 with the component parts separated. The safety interlock includes a support pad 114 rotatably mounted on the frame 18 by means of a pin 116. The pad 114 includes an integrally molded leaf-type spring 118, which abuts against a rib molded integral with the frame, and a flange 122 which is biased by spring 118 into contact with a rib 124 on the lower portion of the frame 18. Flange 122 comes into contact with a rib 126 of the frame 18 when the launching implement is placed on an appropriate supporting surface and the pad 114 rotates clockwise against the force of the spring 118. A pin 128 mounted on an upwardly directed ear 130 of the pad 114 engages in a slot 132 on an interlocking arm 134. An elongated slot 135 is provided in the interlocking arm 134 to slide the arm along a pair of pins 136 and 138 which are molded as part of the frame 18. The interlocking arm 134 is provided with an L-shaped rear end 140 such that a blocking pad 142 on the end of the trigger 120 cannot move downward unless the interlocking arm 134 is in its forwardmost position.

Another pad 144 is provided toward the front end of the frame 18 and is rotatably mounted on a pin 146 which is mounted on a depending arm 148 of the frame 18. A cam surface 150 is provided on an arm 152 of the pad 144 such that during rotation of the pad 144 about the pin 146 the cam surface 150 contacts a cam follower which is rotatably mounted on a second elongated interlocking arm 162 by means of a pin 164.

The cam follower 160 is provided with two upwardly directed arms 165. The two upwardly directed arms 165 can protrude into the firing compartment 67a through a hole 166 in the bottom of the firing compartment. When the firing compartment 67a is loaded with a toy vehicle 14 and shell 16 combination the tips of the arms 165 abut against the bottom of the car 54 as seen in FIG. 2. This point of contact acts as a fulcrum for the cam follower 160 such that when the pad 144 is rotated clockwise the cam follower (through pin 164) causes the interlocking arm 162 to move to the left in the direction of arrow C (FIG. 2).

The interlocking arm 162 is provided with a slot 167 which is in slidable engagement with a pin 168 on the frame 18. A second slot 170 is provided in the interlocking arm 162 for slidable engagement on pins 136 and 138. As best seen in FIGS. 4 and 7, the interlocking arm 162 is provided with a U-shaped portion 174 at its rear end (the left as seen in FIG. 7) such that the pad 142 of the trigger 20 cannot be moved downward unless the pad 144 rests on a flat surface. FIG. 4 shows the proper alignment between the interlocking arms 134 and 162 to enable the trigger 20 to be pulled.

The cam follower 160 performs an additional function of preventing the trigger from being pulled when no vehicle is loaded in the firing compartment or when a foreign object not of the size and shape of the toy vehicle 14 is placed in the gun for firing. More particularly, when no vehicle is in the firing compartment 67a, the cam follower 160 will move upwardly through the hole 166 into the firing compartment through the bottom of shell 16 and thereby cause the safety interlocking arm 162 to move to the right in the direction of arrow D (FIG. 2) by the force of a spring 180. Spring 180 is attached to a hook 182 depending from the interlocking arm 162 and is connected to a pin 184 on the frame 18. Thus, the rear end of the interlocking arm 162 will block downward movement of the pad 142 on the trigger 20, and the spring biased plunger 38 cannot be released when the firing compartment does not contain a toy vehicle. To the same extent, if foreign objects, such as dangerously small objects such as penoils or the like. are placed in the gun for firing, the cam follower 160 again will move upwardly through hole 166 and either lift the foreign object or move it to one side and again prevent the gun from firing.

As an additional safety feature, a spring biased latch 190 is provided with a handle 191 for hand operation by the user. The latch 190 is mounted in an elongaged slot 192 in the side of the frame 18 and held in position by a retainer bushing 193. The latch 190 is biased toward the rear of the launching implement 12 by a spring 194 connected between a hook 195 on the latch on a tab 196 on the housing 18. The trigger 20 is provided with an extended rib 197 which contacts the latch 190 and blocks the movement of the trigger 20 unless the safety latch is pushed and held forward in the direction of arrow E. This prevents a user from holding the *gun" pointed upwardly while depressing the pads I14 and 144 and pulling the trigger. Yet a third hand would be necessary to release the safety latch 190.

FIG. 5 shows the launching implement after it has been fired and when it is not resting on a flat surface. As can be seen, the pads 114 and 144 have rotated counterclockwise thus causing the interlocking arms 134 and 162 to move to the right as shown in the drawings to block the pad 142 on the trigger 20. Thus. as shown in this position the trigger cannot be pulled and the spring biased plunger 38 cannot be released while the launching implement is not resting on the floor or other appropriate supporting surface.

The launching implement 12 is fired by pulling the trigger 20 which releases the plunger 38. The front tip 65 48 of the plunger then strikes the rear of the vehicle body 90 through aperture 199 in the rear of shell 16 causing the vehicle to travel down the ramp and out 5 end of the bolt housing 42 engages with the circular disc-like flange 78 on the rear of the shell 16 to withdraw it from the firing chamber 67a. A leaf-hook spring 202 engages circular flange 78 of the shell 16 as it moves backward in the direction of arrow F (FIG. 6)

l0 and causes it to rotate in the direction of arrow G (FIG.

6) and move through the opening 68 in the side of the launching implement. The launching implement is then ready to be reloaded with another toy vehicle and shell combination.
